"Cheers to the longest engagement ever. I like that we don't feel pressure, I like that we have taken our time, I like that we still don't have a date set, and I kind of like you," Kaitlyn captioned her mini Insta slide show. "Best 2 years ever. Happy Anniversary Shawn B. I love you! Swipe for a couple oldie pics that make me smile. We look like babies."

Booth echoed the same sentiment in his Insta photo, which is a gorgeous pic of Kait. "I am one lucky guy to have been able to spend the last two years of my life with this beautiful, intelligent, funny, strong, and bad ass woman! Thank you for the greatest 2 years, thank you for being you, and thank you for, well ya know, Riiiiickk."

While the couple hasn't quite set a wedding yet, they did announce a huge plan for their future. In late March, Bristowe announced she'd made the decision to freeze her eggs.

"I'm freezing my eggs. And giving them to Whitney and Ova to babysit," Bristowe announced on Twitter. "I'm taking control of my future! As a woman there's always pressure to have babies, and this puts my mind at ease for when I'm ready. This is kind of a backup plan for us and for us to feel comfortable."

"I think a lot of women feel pressure to have kids, especially when you get engaged. And for me, I'm like, I don't want that pressure on myself," Bristowe defended during an interview with Good Morning America. "This is kind of a backup plan for us and for us to feel comfortable. It's kind of like insurance."
